Impact of cyber-attacks on islanded microgrid operation

摘要: The prevalent integration of highly intermittent renewable distributed energy resources (DER) into microgrids necessitates the deployment a microgrid controller. In absence main electric grid setting network voltage and frequency, power management becomes more challenging, accentuating need for centralized controller that, through communication links, ensures smooth operation autonomous system. This extensive reliance on information technologies (ICT) creates potential access points vulnerabilities that may be exploited by cyber-attackers. paper first presents typical configuration operating in islanded mode; elements, primary secondary control functions power, load are defined. transferred from central to coordinate dispatch DERs is provided along with deployable protocols. arising such cyber-attacks exploiting them described. impact these attacks was shown dependent characteristics, location target cyber-attack, as well control. A real-time hardware-in-the loop (HIL) testing platform, which emulates featuring DERs, an storage system (ESS), diesel generator controllable loads used case study order demonstrate various cyber-attacks.
